Sahih Bukhari Volume 3, Book 47, Hadith 2498

حَدَّثَنى عَمْرُو بْنُ عَلِيٍّ، حَدَّثَنَا أَبُو عَاصِمٍ، عَنْ عُثْمَانَ يَعْنِي ابْنَ الأَسْوَدِ، قَالَ أَخْبَرَنِي سُلَيْمَانُ بْنُ أَبِي مُسْلِمٍ، قَالَ سَأَلْتُ أَبَا الْمِنْهَالِ عَنِ الصَّرْفِ، يَدًا بِيَدٍ فَقَالَ اشْتَرَيْتُ أَنَا وَشَرِيكٌ، لِي شَيْئًا يَدًا بِيَدٍ وَنَسِيئَةً، فَجَاءَنَا الْبَرَاءُ بْنُ عَازِبٍ فَسَأَلْنَاهُ، فَقَالَ فَعَلْتُ أَنَا وَشَرِيكِي زَيْدُ بْنُ أَرْقَمَ، وَسَأَلْنَا النَّبِيَّ صلى الله عليه وسلم عَنْ ذَلِكَ فَقَالَ ‏"‏ مَا كَانَ يَدًا بِيَدٍ فَخُذُوهُ، وَمَا كَانَ نَسِيئَةً فَذَرُوهُ ‏"‏‏

Narrated By Sulaiman bin Abu Muslim : I asked Abu Minhal about money exchange from hand to hand. He said, "I and a partner of mine bought something partly in cash and partly on credit." Al-Bara' bin 'Azib passed by us and we asked about it. He replied, "I and my partner Zaid bin Al-Arqam did the same and then went to the Prophet and asked him about it. He said, 'Take what was from hand to hand and leave what was on credit.'"
